Application filed February 2, 1928. Serial No. 251,369.

This invention relates to window constructions, and has more particular reference to an improved construction'of that type wherein vertically sliding sashes are so mounted as to be readily swung inwardly and downwardly so that convenient access may be had thereto for cleaning and repair.

The primary object of the present invention is to provide a sash construction of the above type which is extremely simple and durable in construction as well as eflicient and reliable in use.

A more particular object is to providean improved sash construction of the above kind in which a main outer window frame section is provided for being fixed in the opening of a building wall, and in which an inner supplemental frame section carries vertically slidable sashes and is. hinged at its lower end to the main outer frame section for swinging vertically into orout of the latter, the inner supplemental frame section being provided with sash weight guides at the sides thereof so that disconnection of the sash cords from the sash weights is rendered unnecessary when the inner supplemental frame section is swung inwardly and downwardly to provide for convenient access to the sashes. v

Still another object is to provide a window construction of the above kind in which a simple and efficient eounter balancing means is provided for the swinging inner supplemental frame section, whereby the latter may be swung into Or out of the outer main frame section with the expenditure of a minimum amount of effort, and whereby .the inner supplemental frame section may be adjusted to any desired inwardly and downwardly swung position.

Other objects will become apparentas the nature of the invention is better understood, and the same consist in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing: I

Figure 1 is an inside elevational view of a window construction embodyingthe present invention with the inner supplemental frame section in its normal upwardly swung operative position within the main outer frame section;

Figure 2 is a side elevational view thereof,

partly broken away and in section, and with the inner supplemental frame section swung inwardly and downwardly to facilitate access to the sashes; and

Figure 3 is an enlarged fragmentary vertical section taken substantially upon line 3-3 of Figure 2.

Referring more in detail'to the drawing,. the present invention embodies a main outer having'a pair of inner grooves 13 defined bya parting strip 14 and inner and outer jambs 15 and 16 and in which the upper and lower sashes 17 and 18 are respectively vertically slidable, The inner frame section is thus mounted at its lower end to swing vertically upon a horizontal axis upwardly and outwardly into or downwardly and inwardly out of the main outer frame section, and it will be seen that when the inner supple mental frame section is swung inwardly. and" downwardly to a substantially horizontal position as shown in Figure 2, the sashes will be readily accessible for cleaning or repair.

Mounted in openingsprovided in the upper end portions of the side members 11 of the inner supplemental frame section, coincident with the guide grooves 13,'are suitable guides or pulleys 19 over which the sash cords 20 pass, the inner ends of the sash cords being suitably attached to the sides of the sashes 17 and 18 near the tops of the latter as is generally well known in the art, and the outer ends ofthe sash cords being attached to suitable sash weights 21 disposed at the outer sides of the walls 11 and freely vertically movable in the respective guideways 22 of hollow partitioned guides 23"fixed to the sidewalls 11 of the inner frame section. It will thus be seen that the guides and sash weights will swing inwardly and downwardly with the inner frame section so that disconnection of the sash cords from the sash weights is rendered unnecessary when positioning the inner frame section to have ready access to the sashes. The guides 23 preferably terminate at theirupper ends directly below the guides or pulleys 19 so'that access may be had to the sash cords and sash weights whenever desired. Further, the guides 23 are preferably in the nature of metallic members suitably fastened to the wooden side walls 11 so as to be capable of removal when required. It will be noted that the front or outer wall 7 of the main. outer frame section projects inwardly of the walls 5 and (3 so as to provide an abut ment for and conceal the guides 23 when the inner supplemental frame section is in its upwardly swung position. The inner supplemental frame section further has an inner wall, 2 1 which projects outwardly of thewalls 11 and 12 to. abut the inner edges of the walls a and 6 when the inner frame section in its upwardly swung position, the wall 241- being located at the inner sides of the guides 23. Thus, when the inner sup plemental frame section is in its upwardly swung position, a finished and neat appearing window frame construction is had which may of course be made to appear as an ordinary window construction when the hinges 10 are suitably concealed or employed in a relatively small and ornamental form. The hinges 10 being located at the forward or outer portion of the projecting part 9, the latter will form an abutment for limiting the downward swinging movement of the inner frame section as shown in Figure 2, to a horizontal position.

The inner frame section is of a height so that its top wall 12 will normally be located spaced below the top wall 5 of the outer frame section, and mounted horizontally within this space of the main outer frame section is a conventional spring roller 25 similar to rollers commonly used for window shades, with the pawls and ratchets removed. A flexible member or cord 26 is attached intermediate its ends to the central partof the spring roller 25 and has its ends attached as at 27 to the top wall 12 of the inner frame section adjacent the sides of the latter. The spring'roller 25 is so mounted that when. the inner frame section is swung inwardly and downwardly to unwind the cord portions or strands of the cord 26 therefrom, its spring is placed under tension,"the tension being relieved by the winding of the cord strands thereon when the inner frame section is swung upwardly and outwardly. In this way the inner frame section is effectively balanced so that a minimum amount of effort is required in swinging the inner frame section to and from its operative position within the outer main frame sectio11.Furtl1e1-, this construction will permit the inner frame section to be left at any desired adjustment between its limits of swinging movement. As shown, the pintles at the ends of the roller 25 are engaged with suitable supporting brackets 28 mounted on the inner side of the front wall 7 directly beneath the top wall 5. A suitable has'p 29 may be provided upon the free edge of the inner wall 24 of the inner frame section at one side of the latter in position to engage a keeper 30 carried by the adjacent side wall 6 of the outer frame section when the inner frame section is swung to its normal operative position within the main frame section of the window. This will releasably hold the inner frame section in its normal position in an obvious manner. As the construction at both sides of the frame is the same, the construction at only one side illustrated in the drawing and itis believed that this willbe sufficient to enable a clear understanding of the invention. In. other words, thesash cords, sash cord guides, sash weights and sash weight guides are provided at each side of the window frame in the manner illustrated with respect to one side in the drawing.
